Abstract

We have developed a new teleradiology system that provides a fast response and secure data transmission while using N- ISDN communication and an ISC magneto-optical disk that is specialized for medical use. The system consists of PC-based terminals connected to a N-ISDN line and the ISC disk. The system uses two types of data: the control data needed for various operational functions and the image data. For quick response, only the much smaller quantity of control data is sent through the N-ISDN during the actual conference. The bulk of the image data is sent to each site on duplicate ISC disks before the conference. The displaying and processing of images are executed using the local data on the ISC disk. We used this system for a trial teleconsultation between two hospitals. The response time needed to display a 2-Mbyte image was 4 seconds. The telepointer could be controlled with no noticeable delay by sending only the pointer's coordinates. Also, since the patient images were exchanged via the ISC disks only, unauthorized access to the patient images through the N-ISDN was prevented. Thus, this trial provides a preliminary demonstration of the usefulness of this system for clinical use.
